LOS ANGELES — A big rig crashed off the side of a freeway transition road in the Boyle Heights area, spilling some fuel and resulting in the closure of the connector road while crews worked to repair guard rails.

The crash was reported about 6 a.m. on the connector from the westbound San Bernardino (10) Freeway to the southbound Santa Ana (5) Freeway, the California Highway Patrol reported. One person was treated for an unspecified injury.

The big rig ended up on its side, wedged in an area below the roadway surface and adjacent to a freeway abutment structure.

A hazardous-materials team was sent to clean up fuel that spilled from the truck’s tanks.

The closure was expected to continue until late afternoon, the CHP reported.
